Removed a bunch of unneeded CSS/JS links

Also moved all JS includes to bottom of <body>
Put JS includes back in <head>

JQuery stuff kind of needs to be loaded by the time we render the page
so we can do cool stuff like fades :(
Changed "uploaded!" text after completing a file upload to "parsing"

This text only shows for a split second immediately before the redirect
happens, so "parsing..." is a bit more informative, though arguably less
accurate
The permalink notice's JS now only gets output when we need to display
it
